At the recent SMTOWN concert in Chile, Irene joined Super Junior for "Lo Siento" stage. Several netizens claimed Leeteuk made Irene uncomfortable by adding unnecessary touches during the dance.
However, fans are defending Leeteuk, stating the original choreograph requires him to put his hands on the partner's waist.
Many are now demanding an apology for Leeteuk, using the hashtag #ApologizeToLeeteuk.
Leeteuk also seems to be frustrated with the issue as he 'liked' an #ApologizeToLeeteuk post on Instagram.
